ieee1394: write broadcast_channel only to select nodes (fixes device recognition)
Some old 1394-1995 SBP-2 bridges would hang if they received a broadcast write request to BROADCAST_CHANNEL before the config ROM was read. Affected devices include Datafab MD2-FW2 2.5" HDD and SmartDisk VST FWCDRW-V8 portable CD writer. The write request is now directed to specific nodes instead of being broadcast to all nodes at once, and it is only performed if a previous read request at this register succeeded. Fixes an old interoperability problem which was perceived as a 2.6.14-specific regression: http://marc.theaimsgroup.com/?t=113190586800003 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Jody McIntyre <scjody@modernduck.com> (cherry picked from 61c7f775ca25ccfc0e51486103a724fb1a3a08f2 commit)
